The 2018/2020 Combined IR served as the first large scale test of the tools that the IR programming team has been developed. We knew we were in for a big data challenge…but exactly how big was it?
Our query of EPA’s Water Quality Portal for the IR period of record pulled up 1,362,335 data records (that’s more records than there are people in the Salt Lake Valley) from 3,237 monitoring locations throughout the state. However, DWQ did not collect the data alone: we reviewed and assessed data records from 17 different organizations.
